    6LM7/ 6LM7A HARDWARE INSTALLATION 3.1. UNPACKING The mainboard package should contain the following: The 6LM7/6LM7A main board. USER'S MANUAL for main board. Cable set for IDE, Floppy devices. CD for main board Utility. (Bus Master + Sound Driver) The main board contains sensitive electric components, which can be easily damaged by static electricity, so the main board should be left in its original packing until it is installed.
